Hi everyone, This is my very first forum post!
I’m looking for an email app to replace MS Outlook that is able to import & share MS Contacts etc across my Desktop PC (Win 7) + Laptop(Win 10) + 2x iPhone 6S (+ possibly a Samsung Tab-S).
All currently working ok (with same email address) but need them to share/sync MS Contacts that currently only reside on my PC.
Is this possible? I'm reasonably computer literate, but definitely not a tech nerd with email set-up etc and find it all a bit of a nightmare.

Not sure whether to expect a plethora of competing options, or a few simple "Cant' be done"s, or "It's complicated".

If you have an Outlook.com, Office 365, or Exchange account the easiest way is to just install the Outlook app on the iOS and Android devices. You can access your Microsoft email account from your PC’s via the outlook.com website or with the Outlook application installed on the PC. You can read and send email, access your contacts, use your calendar, and share files across all of these devices. You can also use the Microsoft OneDrive cloud storage system. Access to all of these features across all of your devices and PC’s is one of the main Microsoft features.

As Bill noted above, use a webmail platform and you will be able to access your email anywhere. Outlook.com works well, but you can also import all of your Microsoft contacts quite easily into Gmail and go that way. I've used both Outlook.com and Gmail and prefer Gmail. Just do a one-time export of your contacts and calendar and then a one-time import into Gmail and you are good to go. The Google apps for iOS work well too.

If you have an outlook or gmail account, you should export the contacts from outlook then import them into webmail. They will be available on all devices when you use webmail, gmail app, etc. We need to know which email service you use.
